Gan weight initialization effect

WebJan 17, 2024 · There are two methods here: we can either initialize the weights to zero or assign them randomly. Initializing all weights to 0: This makes your model similar to a linear model. All the neurons and every layer perform the same operation, giving the same output and making the deep net useless. WebMar 22, 2024 · This makes it hard to decide which weights to adjust. # initialize two NN's with 0 and 1 constant weights model_0 = Net (constant_weight=0) model_1 = Net (constant_weight=1) After 2 epochs: Validation Accuracy 9.625% -- All Zeros 10.050% -- All Ones Training Loss 2.304 -- All Zeros 1552.281 -- All Ones Uniform Initialization
